The impact of gigafire on vegetation structure, terrestrial vertebrate abundance and diel activity

open access: yesOikos, EarlyView.
Fire regimes are shifting around the world due to climate and land‐use change, resulting in an increased frequency of large and severe wildfires. However, the impact of extreme wildfire events on animal species remains poorly understood. Particularly lacking is an understanding of how fire affects animal behaviour.

Effects of boreal ground layer shrubs and bryophytes on the diversity, biomass and composition of lichen communities across contrasting ecosystems

open access: yesOikos, EarlyView.
There has been much recent interest in understanding how abiotic factors such as light, nutrients, and soil moisture affect the composition and biomass of lichen communities. Meanwhile, whether and how ground layer vegetation such as bryophytes and shrubs also influence lichen communities have received much less attention, particularly regarding how ...

Relatedness, trait evolution, and climatic niche divergence in mammalian island endemics

open access: yesOikos, EarlyView.
Island mammals have influenced ecological and evolutionary theory since Darwin, and many of them provide textbook examples of the dramatic morphological evolution that often occurs in island communities. However, patterns of evolution in the climatic niches of island mammals have yet to be fully explored.

A Test of Spectroscopic Age Estimates of White Dwarfs Using Wide WD+WD Binaries

open access: yesThe Astrophysical Journal
White dwarf stars have been used for decades as precise and accurate age indicators. This work presents a test of the reliability of white dwarf total ages when spectroscopic observations are available. We conduct follow-up spectroscopy of 148 individual
